Brad: Kids Saved Me

Brad Pitt’s found a cure for sadness – kids.

He’s told US TV show Good Morning America – their version of GMTV – being a Dad is his finest hour: "It's the greatest thing I've ever taken on."

"It's the most difficult, the most rewarding and the most fun. I think this is the greatest thing I could possibly achieve, and hats off to all the parents out there."

"Kids, they say the funniest things I've ever heard," he said. "They're the funniest people I've ever met."

He added: "One of the things I'm most happy about for my kids is that they have a mother, I think, because she's amazing."

Brad – who is promoting his new movie called The Assassination of Jesse James – also revealed that filming brought some not so happy memories of his own childhood.

He explained: "Jesse's from the same area that I'm from."

"I was surprised how much that meant to me in the end, to do something that had a connection with home."
